* where '''x''' is the angle in Radians

* by default Calci use Radian as angle
* by default Calci use Radian as angle
[[Manuals/calci/COSEC| COSEC]] can be used if the angle is in Radians.
[[Manuals/calci/SIN| SIN]] can be used if the angle is in Radians.

*This function is used to obtain the Cosecant value of 'x' in degrees.<br/>
*This function is used to obtain the Cosecant value of 'x' in degrees.<br/>
*It is the reciprocal of SIN function i.e, '''COSEC(x) = 1 / SIN(x)'''.<br/>
*It is the reciprocal of SIN function i.e, '''SIN(x) = 1 / COSEC(x)'''.<br/>
*In a right angled triangle '''COSEC(x) = Hypotenuse / Opposite side'''.<br/>
*In a right angled triangle '''SIN(x) = Opposite side / Hypotenuse'''.<br/>
*To obtain the value in Radians multiply with PI()/180 or use COSEC function COSEC(X)
*To obtain the value in Radians multiply with PI()/180 or use SIN function SIN(X)
*DCOSEC returns NaN if 'x' is not real
*DSIN returns NaN if 'x' is not real
The angle can be a single value or any complex array of values.
The angle can be a single value or any complex array of values.
The following example shows how DCOSEC is applied to an array of numbers containing numbers 1..10.
The following example shows how DSIN is applied to an array of numbers containing numbers 1..10.
*Type =1..10@DCOSEC in Calci
*Type =1..10@DSIN in Calci
*Type =1..10@DCOSEC or 1..10@DCOSEC in ZOS
*Type =1..10@DSIN or 1..10@DSIN in ZOS
